                    <p>
                        DisSim is a web system for exploring similar diseases and discovering relationships among diseases and therapeutic chemicals (TCs). The four-layer architecture including DATABASE, ALGORITHM, TOOLS, and VIEW is described as the following figure.
                        <br /> (1) <span id="DATABASE">DATABASE layer</span>. This layer stores <a href="./resources.jsp#DiseaseOntology" style="text-decoration: underline; color: #EB1D1D;" onMouseOut="this.style.textDecoration='underline'" onMouseOver="this.style.textDecoration='none'">Disease Ontology
					(DO)</a>, disease-related genes, functional associations between genes, and TCs of diseases. Among them, DO, disease-related genes, and functional associations between genes are used by ALGORITHM layer for calculating similarity between diseases.
                        <br /> (2) <span id="ALGORITHM">ALGORITHM layer</span>. Five algorithms of measuring similarity between diseases have been implemented, which include <a href="./resources.jsp#Resnik" style="text-decoration: underline; color: #EB1D1D;"
                            onMouseOut="this.style.textDecoration='underline'" onMouseOver="this.style.textDecoration='none'">Resnik</a>, <a href="./resources.jsp#Lin" style="text-decoration: underline; color: #EB1D1D;" onMouseOut="this.style.textDecoration='underline'"
                            onMouseOver="this.style.textDecoration='none'">Lin</a>,
                        <a href="./resources.jsp#Wang" style="text-decoration: underline; color: #EB1D1D;" onMouseOut="this.style.textDecoration='underline'" onMouseOver="this.style.textDecoration='none'">Wang</a>, <a href="./resources.jsp#PSB" style="text-decoration: underline; color: #EB1D1D;"
                            onMouseOut="this.style.textDecoration='underline'" onMouseOver="this.style.textDecoration='none'">PSB</a>, and <a href="./resources.jsp#SemFunSim" style="text-decoration: underline; color: #EB1D1D;" onMouseOut="this.style.textDecoration='underline'"
                            onMouseOver="this.style.textDecoration='none'">SemFunSim </a>.
                        <br /> (3) TOOL layer. Two tools including SimDisExplore and SimPDExplore have been provided for exploring the similarity score between diseases. SimDisExplore is used to explore similar diseases for an inputted disease term. In
                        comparison, SimPDExplore calculates the similarity for a given pair of diseases. Both SimDisExplore and SimPDExplore provide the function for comparing TCs of diseases. <br /> (4) VIEW layer. Webpages are provided for viewing the
                        results. It shows the similarity of pair-wise diseases and the p-value of the similarity score. It also provides network visualization of relationships among TCs and a pair of similar diseases. <br />
